After the press conference, Bloomberg attempted to give a high-five to a 7-year-old girl — but was rebuffed. “She left him hanging,” laughs an eyewitness.

New York students math scores stayed mostly flat on the most recent national tests, calling into question the big gains the same students have posted on state exams.

Scores on the National Assessment of Educational Progress math exams show little change for fourth- and eighth-graders in New York.

The percentage of fourth-graders scoring proficient or higher fell from 43% in 2007 to 40% this year.

The state math exams have painted a very different picture of student achievement.

The City Council appears to be trying to stand up to Janette Sadik-Khan, the Bloomberg administration’s relatively radical and innovative transportation commissioner who has rapidly closed down car lanes and replaced them with bike lanes and open space across the city.

. . .

The secret to her magic: the transportation commissioner has broad power to do as he or she likes with the roadways without subjective outside approvals, as, traditionally, such commissioners simply treated roads as roads. But by treating the roads more like canvases of open space that happen to accommodate cars, she is able to achieve quick, tangible results that are relatively low budget, and to go forward without approval from the City Council. (By contrast, the Council must approve any major land-use changes on private or city-owned land, making it far more difficult to quickly implement any major changes.)

[Two City Council] bills would mandate the community board appearances and add new requirements for timeline (30 to 60 days of review), set up public hearings, and require DOT to provide certain information about its planned projects.

With decreased capacity and a small percentage of extremely high ticket prices, the Yankees totaled just seven sellouts in the first year of their new stadium and experienced a 13% drop in attendance in 2009.

Grandparent Gwen Barrett said the neighborhood has always been edgy.

“That kind of stuff here is anticipated,” she said.

Still, “I definitely wouldn’t want to bring my grandkids here,” she added.

The sight of the Phillies’ Pedro Martinez pitching against his former team was supposed to be the most unusual aspect of the game. But that notion was quickly proved wrong before the top of the first inning was over, only to be reinforced exactly three hours later when the game ended on an unassisted triple play with the potential tying runs in motion. It was the first unassisted triple play to end a game since 1927, and only the 15th in major league history, according to the Elias Sports Bureau.

In 2005, the union broke with its tradition of endorsing Democrats and backed Mr. Bloomberg, then a Republican, privately arguing that the mayor was likely to trounce a weak field of Democratic candidates.

Many expected the district council to do the same this time, especially since Mr. Bloomberg appears to be steamrolling toward re-election and granted DC 37’s workers back-to-back 4 percent raises last fall, despite the economic crisis.

. . .

In a statement, Howard Wolfson, a spokesman for Mr. Bloomberg’s campaign, said: “DC 37 opposes pension reform, mayoral control of schools, and wants the city to hire more employees, even in a time of fiscal crisis. This is their job, so we understand their position. But these are clearly not things that the mayor could agree to, and so it’s not surprising that they would endorse Mr. Thompson.”

“The real question,” he added, “is what promises Mr. Thompson made them and how much his promises will cost taxpayers.”

Wolfson, of course, is the post-modern political operative: Basically he’s telegraphing to us, “If I were being paid by Democrats, as has been the case for my entire career, I would have simply substituted ‘Bloomberg’ for ‘Thompson’ and had the same message.” It’s brilliant, in fact.

In a stunning lapse of airport security, surveillance cameras at La Guardia Airport failed to capture even a single frame of the dramatic moments when would-be suicide bomber Scott McGann tried to blow himself up and two hero cops wrestled him to the ground, The Post has learned.

. . .

Investigators made the shocking discovery after they retrieved tape from Port Authority cameras, fully anticipating watching the near tragedy unfold and ultimately using it as evidence against the mentally ill terrorist wannabe.

But when they rolled the tapes, the entire episode was nowhere to be found because of a glaring lack of surveillance coverage. “There was zilch,” one flabbergasted law-enforcement source said.

“There was nothing of use,” said another.

The sources also disclosed that what little video they did recover from cameras in the general vicinity was “grainy,” of “poor quality” and basically “showed the tops of people’s heads.”

In fact, PA investigators and prosecutors at the office of Queens DA Richard Brown agreed that the tapes were of no forensic value and “unusable” against McGann.
